For people living in a small apartment in city center without balcony like me, we don't have any "safe" place to store it. I got three 5200mAh Lipos and I put them in metal ammo box and put the box near the entrance where there are ceramic tile on the floor. Everywhere else there is wood on the floor. I assume this is the safest place I can store my lipo... I don't have any spare plan if something goes wrong. But since the dangerous things often happen when charging and discharging, I'm not that worried.
